Salam Alaikum Ustadh; I have Waswaas in Salaah about validity of my prayer. Please could you provide a source or video link that explains “All things that invalidate Prayer”. Through this; I can convince myself that my salah is valid. This is disrupting my whole life & I am in depression Ustadh.

Ustadh AbdulAziz al-Haqqan

There isnt any video that will help u the problem is not with ur prayer as it is valid the problem is that u won't and don't sesriously and decisively want to stop thinking about waswas as that is the Prophetic curs for it.
